SUCTION CLEANING-MACHINE.

Paten'ted'Mar. '7, 1911.

' Application tiled January 27, 1910. Serial No. 540,391.

States, residing at Washington, in the District of Columbia, have invented certain new and. useful Improvements in Suct1on Cleaning-Machines, of which the following is a specification, reference being had therein to'the accompanying drawing.

This invention relates to improvements in suction cleaning machines, and has special reference to a new and improved form of suction head and self-adjusting attachment therefor, for use in such machines and especially adapted for the forms of suction cleaning machines wherein the body of the machine rests upon the"fl.oor, While the suction head rests independently of the machine though carried thereby. That is the suction head is raised by the action of the irregularities of the surface traversed and falls of its own weight to yielding-1y. cont-act or engage said surface. In other words, we provide a substantially vertical tubular sup port, which is attached to and in communi* cation with the dust collecting casing of the machine, and has slidably and rotatably connected thereto a suction head.- The suction head is thereby permitted to rest lightly upon the surface at all times and free from the weight of the machine, or pressure exerted thereon, and thus to smoothly glide over the surface traversed, without in any manner retarding the motion of the machine.

To clearly understand the details of the construction, attention is invited to the accompanying drawings, in which Figure 1 is'a side elevation of our suction head and its support, attached to the forward portion of a dust collecting casing or machine. Fig. 2 is a topplan view thereof.

Fig. 3 is a longitudinal section through the suction head and support on line m-rc, Fig. 1. Fig. 4 is a similar view to Fig. 1 with the lower end of the suction head sup- Fi 5 is an enlarged detail view of the attachin g device between the head and its tube.

Referringto the drawings :The numeral 1 designates the casing of any form of portable suction clcaner, which as shown in our above mentioned applications, is mounted upon wheels, and is adapted to remain in the samerelative position tothe surface traversed. In order to permit this, the suction head or nozzle'2, must be mounted soas not to chock the machine and impede the free gliding motion of the machine. To do this, we provide-the suction head 2, which is preferably made of wood, such as maple,

ash, hickory, mahogany, or other tough close grained woods, and provide it with-the central elongated slot or mouth 3, the walls 4, being inclined or curved from the slot toward the front and rear of the head to permit the free gliding of the mouth over the carpet, floor or rug.

The mouth opens into the flaring chamber 5, which terminates in the circular aperture or opening 6, for the removable reception of the short collar or sleeve 7, carried by the suction head carrying tube 8, which is slidably and snugly fitted within the lower open end of the goose-neck supporting pipe 9, which is secured to the casing by means of the plate 10. It will thus be seen that the tube 8, is allowed a vertical sliding movement within the lower end of the pipe 9, and the nozzle will also be allowed a swinging movement at each end toward and away from the casing with the tube 8, as a central point or axis, as per dotted lines Fig. 2. We have found by ractice that the rotary action of the tube, assists greatly in the sliding motion between the parts, it being demonstrated that it is easier to move the tube within the pipe by this action than by a straight up and down movement, and we therefore preferto permit this action, which will automaticallybe caused by the movement of the machine as the suction head is pushed or pulled over the surface.

In order to permit the use of various width nozzles .or suction heads, we provide each head with the series of studs or headed pins 11, which are adapted to seat. within the hooks 12, carried by the flange 13 of the tube 8, it simply being necessary to turn the tube 8 until the pins or studs are beyond the ends a of the hooks ,at which time the sleeve 7 may be withdrawn from the head or nozzle, and another nozzle or head substituted.

itself upon the surface traversed of its own weight, or by gravity, we employ the catch 14, which is carried by the tube 8 and is pro-,

vided with the stop 15, which rests upon the inner face of the pipe 9, and is prevented from falling too far by means of the stud or stolp 16, formed upon the pipe 9.

will thus be seen that we provide a selfadjusting suction head and support, which will permit the suction head of its own wei. ht to fall and accommodate itself to the sur ace traversed, or be raised by said surface traversed, this action being automatically accomplished as the suction cleaning.

machine is moved to and fro over the surface.

What we claim, as new is ,1. The combination with a portable suction creating device of a suction head carried by the same, and a connection between the device and the suction head consisting of two tubes, one of said tubes leading from the device and the other from the suction head, the said tubes forming a guiding and telescoping eonnection to present the mouth of thesuction head at all times to the surface being cleaned, and permit elevations in-the surface traversed to impart an upward movement to the suction head.

2. The combination with a portable suetion creating device, of a suction head carried. by the same, and a connectionbetween the device and the suction head, consisting of two tubes,'one of the tubes leading from the device and the other from the suction head, and one of the tubes slidingly and roto and slidably and rotatably connected with said 'pipe.

4. vThe combination with'a portable sue.

tion creating device, of a vertical downwardly opening pipe rigidly connected to the suction creating device, a suction head provided with a tube rigidly connected thereto and slidably and rotatably connected with said pipe, and means for limiting the rotary movement of the suction head.

In testimony whereof we aflix our signatures in presence of two witnesses.
